An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2020-24685 in the wild and no public exploit code.\n\nAffected product: ABB AC500 V2 products with onboard Ethernet. No package-level version data is available, so check the vendor advisory linked from the reference page.\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2020-24685/ (Markdown: https://insights.sbomify.com/CVE-2020-24685/index.md)","id":"CVE-2020-24685","markdown":"https://insights.sbomify.com/CVE-2020-24685/index.md","name":"CVE-2020-24685","record":{"aliases":["GHSA-cvwc-6hv2-wv97"],"analysis":{"component_type":"ics_ot","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"ABB AC500 V2 PLC","requires_auth":"none","summary":"An unauthenticated attacker can send a crafted packet to cause a denial-of-service on ABB AC500 V2 PLCs, requiring physical access to restart.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"ABB","cpe":[{"product":"ac500_cpu_firmware","vendor":"abb"}],"cvss":{"score":8.6,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-770","name":"Allocation of Resources Without Limits or Throttling"},{"id":"CWE-789","name":"Memory Allocation with Excessive Size Value"}],"description":"An unauthenticated specially crafted packet sent by an attacker over the network will cause a denial-of-service (DoS) vulnerability.
